A method and apparatus for detecting static objects and broadside objects in a vehicular radar system is presented. Detection data within a field of view for a host vehicle is acquired. A histogram process is used to determine a presence of at least one of a static object and a broadside vehicle. The histogram process includes generating ratios of a relative velocity of an object (Vr) to host velocity (Vh) from acquired detection data and determining a number of detections which occur at an angle &#x3b1; corresponding to an intersection of two lines with a first line represented by Vr/Vh=0 and a region of a second line within the FOV along which Vr/Vh&#x2260;0. The detections are filtered to identify only those detection points at a first and second predetermined values of &#x3b1;, wherein the identified detections indicate a presence of a static object and/or a broadside vehicle.

Broadside detection system and techniques for use in a vehicular radar

A system and method for generating alert signals in a detection system is described. The system compares data extracted from signals received via receive antenna beams with stored scenarios and determines whether to generate an alert signal based upon the results of the compare operation. The comparison of data extracted from received signals with stored scenarios can be accomplished by using one or more latches to process the extracted data from the received signals. In one embodiment, raw detections are pre-processed to generate so-called field of view (FOV) products. The FOV products are then provided to a tracker. In another embodiment, rather than pre-process the raw detections, the raw detections are instead provided directly to a tracker which processes the raw detections to provide products including, but not limited to, relative velocity and other parameters.

A method for generating a radar detection threshold includes computing a first plurality of percentile values associated with frequency domain values of frequency domain signals. The first plurality of percentile values is used to generate detection threshold values. Apparatus for generating a radar detection threshold includes a first percentile processor adapted to compute a first plurality of percentile values associated with frequency domain values of frequency domain signals. A threshold processor is adapted to use the plurality of percentile values to generate detection threshold values.

System and method for generating a radar detection threshold

An automotive radar system includes a beamformer circuit and a beamcombiner circuit. The beamformer circuit forms a plurality of antenna beams at a plurality of beam ports. The beam combiner circuit receives the beams provided thereto from the beamformer circuit and combines the beams to provide a desired number of beams, with each of the beams having a desired beam shape. In one embodiment, the beamcombiner provides first and second end beams having a beamwidth which is less than a beamwidth of middle beams.
